 white; shell strong and solid, marked with many knobs and ridges. 



The Frog Shell has been recorded from Santa Barbara, Mon-

The Nut-cowry rarely exceeds 2 inches in length, and is 

 marked by a dark brown ring, slightly lighter inside, on the back, 

 with white lips; one of the most beautiful of the Calif ornian shells.

 Diego, Cal., at very low water; also recorded from Chinatown 

 Point, Monterey bay, Cal., and dead specimens — often quite large 

 — are rather abundant at Todos Santos bay and Santo Domingo, 

 Baja Cal., and several fine examples were found by pearl hunters 

 at the latter place at the time of my visit.
